In a medium size bowl, combine the soy sauce, rice wine and cornstarch. Stir until well combined and cornstarch is dissolved in the liquid. Add the beef and mix so that beef is well coated in the marinade. Allow beef to marinate at room temperature for 10 minutes.

Make the sauce:

In a small bowl, combine the chicken stock, oyster sauce, soy sauce, rice wine and cornstarch. Stir until well combined and cornstarch is dissolved in the liquid. Set aside

For the stir fry:

Bring a large pot of water to a boil over high heat. Once the water is boiling, add the broccoli and cook for about 2 minutes. Drain the broccoli. Set aside.

Heat the oil in a large skillet over high heat. Tilt the pan so that the oil coats the bottom of the skillet. Add garlic and sauté until fragrant, about 30 seconds. Add the beef and sauté until beef is slightly brown, but not fully cooked, about 1 and a half minutes.

Add the sauce and bring to a simmer. Add the broccoli and stir so that beef and broccoli are well coated in the sauce. Sauté until beef is fully cooked, about 1 minute. Season with salt and pepper, to taste.

Serve hot.

Notes

When cutting beef, be sure to cut against the grain. It is much easier to cut meat if you place it in the freezer for about 30 minutes prior to slicing it.
